Summer Watermelon and Tomato Salad

This has become a new favorite of mine. I ran across it at a favorite local restaurant, but just recreated it as I sat there and savored the flavors. I never asked them for the recipe, so as far as I'm concerned this is an original. :o)

1 ripe small-medium seedless watermelon diced in about 1 inch cubes (organic tastes better)
2-3 large heirloom tomatoes also diced into about 1 inch chunks/cubes (again, organic tastes better)
bunch of fresh basil or mint, you choose, and finely chopped (I prefer basil)
salt and pepper to taste, approx 1 tsp salt and 1/2 tsp pepper, but do it to your liking
2-3 Tblsp Olive Oil
Optional:
8 oz. Feta (We have a lot of followers who are not entirely vegan, but mainly plant-based so I include these tidbits for them)

Put it all together in a big bowl, chill for about an hour before serving and invite me over to eat it with you! It makes a lot. Will likely be 6-8 servings.
